 THIRD AMENDED AND RESTATED 

LEASE AGREEMENT 

(CREZ ASSETS) 
 This THIRD
AMENDED AND RESTATED LEASE AGREEMENT (CREZ ASSETS) (this “Agreement”) is entered into effective as of December 4, 2015 (the “Effective Date”), between Sharyland Distribution & Transmission Services,
L.L.C. (together with its permitted transferees, successors and assigns, “Lessor”), and Sharyland Utilities, L.P. (together with its permitted transferees, successors and assigns, “Lessee”), and in connection
herewith, Lessor and Lessee agree, covenant and contract as set forth in this Agreement. Lessor and Lessee are sometimes referred to in this Agreement as a “Party” or collectively as the “Parties”. 

Certain capitalized terms used in this Agreement have the meaning assigned to them in Appendix A attached hereto. 

WITNESSETH: 
 WHEREAS,
Sharyland Projects, L.L.C. (“Sharyland Projects”) and Lessee entered into that certain Second Amended and Restated Lease Agreement effective as of December 1, 2014 (as amended, restated, supplemented or otherwise modified from
time to time, the “Second Amended and Restated Lease”), pursuant to which Lessee leased the CREZ Lease Assets from Sharyland Projects; 

WHEREAS, effective as of December 3, 2015, Sharyland Projects merged with and into Lessor, with Lessor surviving and succeeding to
Sharyland Projects’ rights and obligations under the Second Amended and Restated Lease; and 
 WHEREAS, the Parties wish to amend and
restate the Second Amended and Restated Lease to reflect that Lessor is a party and to make certain other changes as set forth herein. 

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt of which is hereby acknowledged,
the Parties hereto hereby amend and restate the terms of the Second Amended and Restated Lease as follows: 
 ARTICLE I 

LEASE 
 1.1
Lease of CREZ Assets. 
 (a) Upon the terms and conditions set forth in this Agreement, Lessor
hereby grants to Lessee the exclusive right to use and operate the CREZ Lease Assets. Subject to necessary regulatory approvals and the final paragraph of Section 1.1(b), this Agreement is intended by Lessor and Lessee to be a master lease of
the CREZ Lease Assets, as they existed as of June 20, 2011 (the “Original Lease Date”), as they have been altered by the completion of the construction of the CREZ Project and as it has been or may continue to be altered or
expanded thereafter by Footprint Projects in which Lessor has an interest or by other additions of assets to this Agreement as Footprint Projects pursuant to Rent Supplements.  

  

					
		  	1	  	CREZ ASSETS LEASE AGREEMENT









 (b) The CREZ Assets shall consist of (x) the original assets leased by Sharyland Projects to
Lessee as of the Original Lease Date, (y) assets that constitute Footprint Projects, other than any such Footprint Projects funded by Lessee pursuant to Section 10.3 (except as otherwise provided in Section 10.3), and (z) any
components of the CREZ Assets that are repaired or replaced pursuant to Section 6.1. The CREZ Assets shall consist of the Transmission Lines, the Collection Stations and each of the following components which are owned by Lessor as of the date
hereof (or that are described within clause (y) or clause (z) above) and that are located within the area depicted on Exhibit A: 

(i) towers and poles affixed to the land, and all necessary and proper foundations, footings, crossarms and other appliances
and fixtures for use in connection with said towers, poles and lines; 
 (ii) overhead, underground and underwater electrical
distribution, transmission and communications lines, together with related ductwork and insulators; 
 (iii) electric
substation and switching facilities, including all associated transformers, circuit breakers, resistors, capacitors, buses, interconnection and switching facilities, control and protection equipment which monitors the CREZ Assets, and the building
housing the foregoing items; 
 (iv) electric meters required to operate the CREZ Assets; 

(v) real estate assets, including real property, interests in real property or real property rights (as defined in
Section 856(c)(5)(B) of the Code and the regulations promulgated thereunder, and not otherwise included in Sections 1.1(b)(i)-1.1(b)(iv) above) owned or leased by Lessor and underlying the CREZ Assets, including, without limitation, easements,
licenses, rights of way and other real property interests located within the area depicted on Exhibit A or such other area as may be depicted in a Rent Supplement; or 

(vi) all other systems or property owned or leased by Lessor, as identified in the uniform system of accounts for major
electric utilities, 18 C.F.R. Part 101, as adopted and amended from time to time by FERC (the “FERC Uniform System of Accounts”) (not otherwise included in Sections 1.1(b)(i)-1.1(b)(v) above). 

The CREZ Assets exclude, for the avoidance of doubt, the Transmission Operation Center and the transmission and distribution related assets included in the
Backup Operations Center located in Amarillo, Texas, which are currently owned by Lessor and leased to Lessee pursuant to the McAllen Lease. Notwithstanding anything to the contrary in this Agreement, the Parties do not intend or agree to enter into
a lease with respect to any Footprint Project or other alteration, expansion or addition to the CREZ Assets (and the Lessee shall not be authorized to use or operate such Footprint Project, alteration, expansion or addition to the CREZ Assets)
unless and until such time as the Parties first execute a Rent Supplement for the underlying Footprint Project and such Footprint Project is placed in service, and such Rent 

  

					
		  	2	  	CREZ ASSETS LEASE AGREEMENT









 
Supplement together with this Agreement shall be treated as a new lease with respect to such Footprint Project. The Parties further agree and acknowledge that a Rent Supplement will be executed
with respect to each Footprint Project before such Footprint Project is placed in service, and references in this Agreement to “CREZ Assets” rely on the assumption that this is the case. 

(c) Notwithstanding anything to the contrary in this Section 1.1, for so long as Lessor is in compliance with its obligation to fund
Capital Expenditures pursuant to Article X, Lessor may notify Lessee of its intention to transfer certain assets that would otherwise constitute CREZ Assets under this Agreement (the “Transferred Assets”) to a TRS. Upon any such
notification, the TRS and Lessee shall negotiate in good faith a lease agreement with respect to such Transferred Assets, on terms and conditions that are comparable to those contained herein, and, upon the execution of such lease, the Transferred
Assets shall no longer constitute CREZ Assets hereunder. 
 1.2 Exclusive Rights. Throughout the Term of this Agreement, Lessee shall
have the exclusive right (a) to operate and use the CREZ Lease Assets for the transmission of electricity in accordance with applicable rules and regulations of all regulatory agencies having regulatory jurisdiction over the CREZ Assets,
including without limitation, the PUCT as well as applicable rules and regulations of ERCOT, TRE, NERC and other Regulatory Authorities, and (b) to utilize the CREZ Lease Assets for other opportunities and uses (provided that such other
uses do not interfere with the current or future transmission and delivery of electricity, Good Utility Practice or Applicable Laws and do not adversely affect the reliability and safety of the CREZ Assets or the ERCOT electric grid). Throughout the
Term of this Agreement, Lessor shall have access to the CREZ Assets at all reasonable times for purposes of inspection and for the purposes of improving, expanding or modernizing the CREZ Assets in accordance with Article X. Except in the case of
emergency, prior to Lessor’s access of the CREZ Assets, Lessor will provide written notification to Lessee’s operations personnel. 

1.3 Absolute Net Lease. This Agreement is intended by the Parties to be an absolute net lease (and, except as otherwise specified
herein, the expenses and costs associated with the lease, license, servicing, insuring, maintenance, repair and operation of the CREZ Assets and the performance of Lessee’s obligations under this Agreement shall be for the account of the
Lessee, unless expressly stated that such expenses or costs are for the account of Lessor or some other Person). Other than as expressly provided herein, (a) Lessee’s obligation to make all payments of Rent as and when the same shall
become due and payable in accordance with the terms of this Agreement shall be absolute, irrevocable and unconditional and shall not be affected by any circumstance or subject to any abatement or diminution by set-off, deduction, counterclaim,
recoupment, agreement, defense, suspension, deferment, interruption or otherwise, and (b) until such time as all Rent required to be paid has been paid, Lessee shall have no right to terminate this Agreement or to be released, relieved or
discharged from its obligation to make, and shall not suspend or discontinue, any payment of Rent for any reason whatsoever. 
 1.4
Waiver by Lessee. Lessee hereby waives, to the extent permitted by Applicable Law, any and all rights which it may now have or which at any time hereafter may be conferred upon it, by statute or otherwise, to modify, terminate, cancel, quit or
surrender this Agreement except in accordance with the express terms hereof. 
 1.5 Quiet Enjoyment. Lessee shall be entitled to the
peaceful and quiet enjoyment of the CREZ Lease Assets, subject to the terms of this Agreement, so long as Lessee is not in default of this Agreement beyond applicable notice and cure periods. 

  

					
		  	3	  	CREZ ASSETS LEASE AGREEMENT









 ARTICLE II 

TERM OF LEASE 
 2.1
Term. Subject to the provisions of Section 2.2 of this Agreement, or as otherwise stated herein, this Agreement became effective on the Original Lease Date and shall continue through December 31, 2020 unless otherwise terminated in a
manner consistent herewith (the “Initial Term”). Thereafter, this Agreement may be renewed for subsequent terms (each, a “Renewal Term” and, collectively with the Initial Term, the “Term”) by mutual
agreement of the Parties; provided, however, that the Rent for any Renewal Term shall be targeted to provide the Lessor with a Comparable Rate of Return on the then-current Rate Base of the CREZ Assets. 

2.2 Approvals upon Expiration or Termination. 

(a) Notwithstanding any provisions to the contrary herein, Lessee shall not surrender, resign, transfer, assign or otherwise cease to be the
operator of the CREZ Assets at any time, including upon the termination of this Agreement or at the expiration of the Term, without first acquiring any necessary regulatory approvals from the PUCT or other Regulatory Authorities regarding such
surrender, resignation, transfer, assignment or cessation of such operatorship; provided that, in the event of expiration or termination, the Parties shall use commercially reasonable efforts to obtain all necessary regulatory approvals of
the transfer of such operatorship as soon as reasonably practicable. 
 (b) During any period of time after the expiration of the
Term or termination of this Agreement but prior to Lessee’s acquisition or receipt of any necessary regulatory approvals with respect to Lessee’s surrender, resignation, transfer, assignment or other cessation of its operation of the CREZ
Assets (such period of time being herein referred to as the “Extended Period of Operatorship”), Lessee shall continue to operate the CREZ Assets and shall continue to pay all Extended Period Rent and perform all of Lessee’s
other obligations under this Agreement; provided, however, that if regulatory approval is not obtained within twelve (12) months of initiation of the approval process and such delay is (a) due to Lessor’s failure to
reasonably pursue such approval, then the amounts payable as Rent will be eighty percent (80%) of such amount, or (b) due to Lessee’s failure to reasonably pursue such approval, then the amounts payable as Rent will be one hundred
five percent (105%) of such amount. 
 (c) Upon the expiration of the Term or termination of this Agreement, Lessee shall use
commercially reasonable efforts to obtain all necessary regulatory approvals as soon as reasonably practicable from the PUCT or other Regulatory Authorities to transfer or assign the CCNs for the CREZ Assets to Lessor or a third party designated by
Lessor and acceptable to the PUCT or other Regulatory Authorities. 
 (d) The obligations of Lessee and Lessor contained in this
Section 2.2 shall survive the expiration of the Term or termination of this Agreement. 

  

					
		  	4	  	CREZ ASSETS LEASE AGREEMENT









 2.3 Purchase Option upon Expiration or Termination. Upon the later of (a) the
expiration of the Term or termination of this Agreement or (b) the expiration of the Extended Period of Operatorship (if any), Lessor shall have the option to purchase from Lessee any equipment or other property, tangible or intangible
(including regulatory assets), owned by Lessee and principally used in connection with and necessary for the operation of the CREZ Assets (including any Nonseverable Footprint Projects owned by Lessee, if any), subject to any required regulatory
approvals. The purchase price for such property or equipment shall be the greater of (i) the net book value thereof plus 10% and (ii) the fair market value thereof as determined by mutual agreement of Lessor and Lessee. If the Parties fail
to agree on the amount of the purchase price, the purchase price shall be submitted to arbitration in accordance with Section 13.7, pursuant to which the Arbitration Panel shall be empowered to determine the amount of the purchase price, based
on submissions by each of Lessee and Lessor. 
 ARTICLE III 

RENT 
 3.1 Rent.
Lessee will pay to Lessor in lawful money of the United States of America which shall be legal tender for the payment of public and private debts, at Lessor’s address set forth in Section 13.8 hereof or at such other place or to such other
Person, as Lessor from time to time may designate in a written notice to Lessee, all Rent contemplated hereby during the Term on the basis hereinafter set forth. If there is a dispute as to the amount of Rent to be paid by Lessee, either Party may
submit the dispute to arbitration pursuant to Section 13.7. However, Lessee shall be required to pay, as and when Rent is due and payable hereunder, the Undisputed Rent until such time as the dispute is resolved by agreement between the Parties
or by arbitration pursuant to Section 13.7. 
 (a) Base Rent: Lessee will pay Lessor an amount of base rent equal to the amount
set forth on the then-effective Rent Supplement, which shall be payable monthly in arrears 45 days after the conclusion of the month. The amount of base rent owed pursuant to this Section 3.1(a) may be supplemented by the Parties from time to
time in accordance with Section 3.2. The amount of base rent payable pursuant to this Section 3.1(a), as supplemented from time to time pursuant to Section 3.2, is referred to as “Base Rent.” 

(b) Percentage Rent: In addition to the Base Rent set forth above, Lessee covenants and agrees to pay to Lessor, as percentage rent, an
annual amount equal to the percent of Gross Revenues during the applicable Lease Year in excess of the Annual Percentage Rent Breakpoint for such Lease Year, all as set forth on the then-effective Rent Supplement. The percentage amounts used for the
calculation of percentage rent owed pursuant to this Section 3.1(b) (the “Percentage Rent Percentages”) may be supplemented by the Parties from time to time in accordance with Section 3.2 to account for additions to the
CREZ Assets. The percentage rent payable pursuant to this Section 3.1(b), as supplemented from time to time pursuant to Section 3.2, is referred to as “Percentage Rent.” 

  

					
		  	5	  	CREZ ASSETS LEASE AGREEMENT









 (c) Percentage Rent Breakpoints: With respect to the Annual Percentage Rent
Breakpoint for each Lease Year: (1) the “First Lease Quarter Percentage Rent Breakpoint” shall be 25% of the Annual Percentage Rent Breakpoint for such Lease Year; (2) the “Second Lease Quarter Percentage Rent
Breakpoint” shall be 50% of the Annual Percentage Rent Breakpoint for such Lease Year; and (3) the “Third Lease Quarter Percentage Rent Breakpoint” shall be 75% of the Annual Percentage Rent Breakpoint for such Lease
Year. 
 (d) Gross Revenues: 

(i) As used in this Agreement, subject to Section 3.1(d)(ii), the “Gross Revenues” of the CREZ Assets shall mean
and include all fees, charges and other revenues, computed without duplication, generated by or otherwise (x) received by or payable to Lessee in connection with or which are the result of the operation of the CREZ Assets (and any assets
related to the CREZ Assets owned by Lessee), as set forth in the FERC Uniform System of Accounts or such other accounts as may be applicable from time to time in which Lessee records its revenues from operation of the CREZ Assets; (y) received
by or payable to Lessee from other opportunities and uses of the CREZ Assets pursuant to Section 1.2(b) hereof; or (z) arising from insurance proceeds for business income lost from an insured event related to the CREZ Assets;
provided that “Gross Revenues” shall not include (1) any payment received by Lessee as CIAC; (2) any items which are of a pure pass-through nature where such items are charged to and collected from customers of
Lessee but which carry regulatory responsibility to remit such collections without offset or deduction to a third party, including, but not limited to, items such as: (A) sales taxes or other charges collected by Lessee on behalf of a taxing
authority; (B) fees, charges and other revenues collected by Lessee that can be specifically traced to any regulatory approved costs incurred by Lessee that have been ordered or permitted by the PUCT to be recovered through Lessee’s rates
such as system benefit funds; (C) fees, charges and other revenues collected by Lessee that can be specifically traced to any deferred costs funded by Lessee that have been ordered or permitted by the PUCT to be recovered through a tariff
rider; and (D) such other items that Lessor and Lessee agree to in good faith are consistent with the foregoing and should be included prospectively in the list set forth in this clause (2) and in the event the Lessor and Lessee cannot
agree on what items should be included on such list, then either Lessor or Lessee may submit such matter to arbitration pursuant to Section 13.7, pursuant to which the Arbitration Panel shall be empowered to determine which such items shall be
included on such list, based on submissions by each of the Lessee and the Lessor; and (3) Revenues Attributable to Lessee CapEx. The term “Unadjusted Gross Revenues” means the amount of Gross Revenue, calculated in accordance
with this Section 3.1(d)(i), without giving effect to the offset set forth in clause (3), above, related to Revenues Attributable to Lessee CapEx. 

(ii) Except as set forth below, all ERCOT Transmission Revenues will be allocated to the CREZ Assets covered by this Agreement based upon the
following formula: Multiply (x) total ERCOT Transmission Revenues received by Lessee by (y) a fraction, the numerator of which is the Transmission Net Plant in Service for the CREZ Assets covered by this Agreement and the denominator of
which is the total Transmission Net Plant in Service for all regulated electric transmission systems owned by Lessor or an affiliate thereof and operated by Lessee or a subsidiary thereof within ERCOT (the “TCOS Allocation”). As of
the Effective Date, all regulated electric transmission systems operated by Lessee or a subsidiary thereof within 

  

					
		  	6	  	CREZ ASSETS LEASE AGREEMENT









 
ERCOT are owned by Lessor or a subsidiary or parent entity thereof. As long as that is the case, Transmission Net Plant in Service and Transmission Gross Plant in service shall be derived
exclusively from the financial statements of Lessor and agreed to by Lessee. If Lessee or any subsidiary thereof operates any electric transmission systems within ERCOT that are not leased from Lessor or an affiliate thereof, then the Parties will
negotiate in good faith an equitable and appropriate mechanism for allocating ERCOT Transmission Revenues based on the Transmission Net Plant in Service of the respective electric transmission systems and in the event the Parties cannot agree on an
equitable and appropriate mechanism, then either Party may submit such matter to arbitration pursuant to Section 13.7, pursuant to which the Arbitration Panel shall be empowered to determine such equitable and appropriate TCOS Allocation
mechanism, based on submissions by each of the Lessee and the Lessor. The most recent TCOS Allocation agreed to by Lessor and Lessee will govern the allocation described in this Section 3.1(d)(ii), which TCOS Allocation may be set forth in a
Rent Supplement, but will not be required to be included in a Rent Supplement to be effective. Either Party may request a revision to such TCOS Allocation, based on the most recent available monthly balance sheet, no more frequently than once every
sixty (60) days or in connection with any Rent Supplement or Rent Validation executed and delivered by the Parties. If the Parties are unable to agree to an allocation, such matter will be submitted to arbitration pursuant to Section 13.7.
“Gross Revenues,” for purposes hereof, will include the amount of such ERCOT Transmission Revenues allocated to the CREZ Assets pursuant to this Section 3.1(d)(ii), plus any other amounts that constitute Gross Revenues pursuant
hereto, minus (without duplication) Revenues Attributable to Lessee CapEx. As of the date hereof, the Parties do not expect that any Lessee revenue, other than ERCOT Transmission Revenues, will be allocated to the CREZ Assets and constitute Gross
Revenues hereunder. 
 (iii) The Parties contemplate that there may be Capital Expenditures for assets that are placed in service and that
are related and fairly allocable to the CREZ Assets and are classified as Lessee CapEx. Unless the Parties agree otherwise based on appropriate factors at the time of the negotiation, Capital Expenditures that qualify as Lessee CapEx will qualify as
Lessee CapEx on the date that the assets developed with such Capital Expenditures are placed in service. In such a case, Revenues Attributable to Lessee CapEx shall be determined and such portion shall be subtracted from Unadjusted Gross Revenues in
order to calculate Gross Revenues. For these purposes, Revenues Attributable to Lessee CapEx shall be targeted to equal that portion of the Unadjusted Gross Revenues collected by Lessee which equals the amount needed to provide Lessee with the
equivalent of a Comparable Rate of Return on any such Lessee CapEx (except that, in determining such Comparable Rate of Return, the Parties will not consider Lessee’s creditworthiness and there will be no Agreed-to-Discount). It is understood
and agreed that such determinations of the Revenues Attributable to Lessee CapEx are intended to provide an accurate and reasonably administrable means of ensuring that the Lessee (and not the Lessor) will receive a Comparable Rate of Return
attributable to the capital invested by Lessee in the Lessee CapEx. The Revenues Attributable to Lessee CapEx shall be determined solely to provide a Comparable Rate of Return on such Lessee CapEx and shall not be determined with reference to, or
with any intention to true up, the effect of any difference between the initially anticipated and the actual return of or on prior Lessee CapEx. The Parties understand that there may be Capital Expenditures that relate to both the CREZ Assets and to
other transmission and/or distribution systems owned or operated by Lessee or an affiliate thereof, and, in such circumstance, the Parties will 

  

					
		  	7	  	CREZ ASSETS LEASE AGREEMENT









 
negotiate in good faith to determine the portion of such Capital Expenditures that constitute Lessee CapEx hereunder. In the event the Parties cannot determine such portion, then either Party may
submit such matter to arbitration pursuant to Section 13.7, pursuant to which the Arbitration Panel shall be empowered to determine such portion of Capital Expenditures that constitute Lessee CapEx hereunder, based on submissions by each of the
Lessee and the Lessor. Lessee agrees to provide Lessor with sufficient information regarding Lessee CapEx so that Lessor can monitor amounts actually spent on Lessee CapEx. If Lessee expects there will be any Lessee CapEx, Lessee may request, no
more frequently than annually, that the Parties determine the Revenues Attributable to Lessee CapEx which relate to such Lessee CapEx for each subsequent Lease Year. Lessee will use reasonable efforts to make such request coincide with a Rent
Supplement pursuant to Section 3.2(a). Each supplement and related determination of Revenues Attributable to Lessee CapEx for any Lease Year which is specified in this Section 3.1(d)(iii) shall be memorialized in the manner specified in
Section 3.2(b). 
 (e) Payment of Percentage Rent: Percentage Rent shall be paid by Lessee to Lessor not later than the date forty-five
(45) days after the end of each Lease Quarter as herein provided. Lessee shall record Gross Revenues in order to provide an audit trail for the Gross Revenues. Lessee shall deliver a written statement to Lessor, accompanied by a CFO
Certificate, within forty-five (45) days after the end of each Lease Quarter, stating (1) the Gross Revenues for that Lease Quarter, (2) the cumulative total through the end of that Lease Quarter of Gross Revenues for such Lease Year,
(3) the Percentage Rent Breakpoint (the First Lease Quarter Percentage Rent Breakpoint, the Second Lease Quarter Percentage Rent Breakpoint, the Third Lease Quarter Percentage Rent Breakpoint or the Annual Percentage Rent Breakpoint for such
Lease Year, as applicable), utilized by Lessee and applicable to Lessee’s calculation of Percentage Rent through the end of that Lease Quarter, and (4) the cumulative total of any Percentage Rent then due and the cumulative total of any
Percentage Rent previously paid with respect to any prior Lease Quarter(s) within such Lease Year. If such CFO Certificate indicates that any Percentage Rent is due for such Lease Quarter (or such Lease Year, as applicable), based upon the
cumulative total of Gross Revenues through the end of such Lease Quarter and the applicable Percentage Rent Breakpoint reflected in such statement, then Lessee shall pay and deliver any Percentage Rent then due with the statement and CFO Certificate
for such Lease Quarter (or such Lease Year, as applicable). With respect to the final Percentage Rent calculation for any Lease Year, Lessee shall receive a credit for any Percentage Rent previously paid with respect to such Lease Year. If the
Percentage Rent payments previously made by Lessee to Lessor for the first three Lease Quarters of a Lease Year, on a cumulative basis, exceed the annual amount of Percentage Rent payable by Lessee to Lessor for such Lease Year, then Lessee shall
receive a credit for such excess amount against the next Percentage Rent payment(s) becoming due and payable by Lessee to Lessor under this Agreement. The applicable Percentage Rent Breakpoint shall also be adjusted pro rata for any partial Lease
Quarters or partial Lease Years at the beginning and/or end of the Term. All statements deliverable by Lessee to Lessor under this Agreement shall be delivered to the place where rent is then payable, or to such other place or places as Lessor may
from time to time direct by written notice to Lessee.

 3.2 Rent Supplements. 

(a) The Parties have executed a Rent Supplement with respect to the Rent in effect as of the Effective Date. This Section 3.2(a)
will not require any amendment to Rent unless the Parties expect Incremental CapEx and the Parties have not previously entered into a Rent Supplement with respect to such Incremental CapEx. If the Parties expect Incremental CapEx (“Expected
Incremental CapEx”), then they will negotiate in good faith to supplement Rent and other matters in accordance with this Section 3.2. In connection therewith, the Parties will negotiate the pre-tax rate of return that Lessor should
earn on such Incremental CapEx, which will be based generally on an agreed-to-discount from the rate of return that public utility companies generally earn in the State of Texas at the time of such Rent Supplement negotiation, adjusted in the manner
agreed to by the Parties (if justified) to take into account the creditworthiness of Lessee at the time of such Rent Supplement negotiation (the “Agreed-to-Discount”). Such discount
will be based on the comparable discount agreed to in connection with the negotiation of rent pursuant to the McAllen Lease and other leases between Lessee and Lessor (or an affiliate thereof), as modified to take into account appropriate factors at
the time of such Rent Supplement negotiation. Such pre-tax rate of return, as determined in accordance with this paragraph, is referred to as a “Comparable Rate of Return.” The following will apply to the determination of the
matters set forth on the Rent Supplement: 
 (i) The Parties will supplement Base Rent and Percentage Rent in a manner
intended to provide a Comparable Rate of Return for Lessor on the Expected Incremental CapEx. Such Comparable Rate of Return will be achieved by a split between Base Rent and Percentage Rent in the proportions requested by Lessor and agreed to by
Lessee. 
 (ii) Unless the Parties agree otherwise based on appropriate factors at the time of the negotiation, Capital
Expenditures will qualify as Incremental CapEx on the date the assets subject to such Capital Expenditures are placed in service (notwithstanding that Capital Expenditures that are included in CapEx Budgets pursuant to Article X are for such
purposes measured based on the date the related Capital Expenditures are incurred). 
 (iii) Notwithstanding anything herein
to the contrary, such supplement shall be determined solely to provide a Comparable Rate of Return on such Expected Incremental CapEx and shall not be determined with reference to, or with any intention to true up, the effect of any difference
between the initially anticipated and the actual return of or on, or the Base Rent or Percentage Rent payable with respect to, the CREZ Assets as in place prior to the additions resulting from such Expected Incremental CapEx. 

(b) The Parties will memorialize the results of all Incremental CapEx supplements and Lessee CapEx supplement negotiations by executing and
delivering a Rent Supplement, which will set forth the amount of contemplated Incremental CapEx, new Base Rent, a new Percentage Rent Schedule, new Revenues Attributable to Lessee CapEx, Lessee CapEx, new TCOS Allocation (if applicable), the
effective date on which such changes will occur and the term of such Rent Supplement (if applicable). In no event will any new Base Rent or new Percentage Rent be payable, or any Revenues Attributable to Lessee CapEx be


  

					
		  	9	  	CREZ ASSETS LEASE AGREEMENT









 
taken into account as a reduction to Unadjusted Gross Revenues, before the assets funded by the related Incremental CapEx or Lessee CapEx are placed in service. The Rent Supplement may also
include the projected in-service date of the Incremental CapEx or Lessee CapEx to which the Rent Supplement applies. Upon execution and delivery of any such Rent Supplement, this Agreement will be deemed amended thereby. If necessary, Exhibit
A will be supplemented to reflect the new assets to be funded by the Incremental CapEx. The Rent Supplement shall have the term set forth therein, not to extend past the then-current Term of this Agreement. At the end of the term of each Rent
Supplement, the Parties shall negotiate a new Rent Supplement for the Lessee CapEx and Incremental CapEx covered by such prior Rent Supplement using the Comparable Rate of Return methodology set forth in Sections 3.1(d)(iii) and 3.2(a).
Notwithstanding the foregoing, the Percentage Rent Percentages and Annual Percentage Rent Breakpoints reflected on such new Rent Supplement with respect to the Rate Base covered by such prior Rent Supplement shall be as set forth on the Percentage
Rent Schedule of such prior Rent Supplement. 
 (c) This Section 3.2(c) sets forth the process by which the Parties may request and
effect Rent Validations. 
 (i) If following the execution and delivery of a Rent Supplement there is a difference in
(I) the amount of actual Incremental CapEx compared to the amount contemplated by the then-effective Rent Supplement, (II) the amount of actual Lessee CapEx compared to the amount contemplated by the then-effective Rent Supplement, or (III) the
placed-in-service date of such Incremental CapEx or Lessee CapEx compared to what was contemplated at the time of the then-effective Rent Supplement then, at any time within two years of the date the Parties agree to a Rent Supplement, either Party
may request a Rent Validation. If there has been such a difference, the Parties will supplement Incremental CapEx, Base Rent, Percentage Rent Percentages, Annual Percentage Rent Breakpoints, Revenues Attributable to Lessee CapEx and/or Lessee CapEx,
as applicable, to what they would have been, at the time of the Rent Supplement, to reflect (1) the amount of actual Incremental CapEx and Lessee CapEx and/or (2) the actual dates such Incremental CapEx and/or Lessee CapEx was placed in
service, but keeping fixed all other relevant assumptions and inputs, including the Comparable Rate of Return. For the avoidance of doubt, in no circumstance will a Rent Validation occur to account for any difference between the initially
anticipated and the actual return of or on the Incremental CapEx and/or Lessee CapEx, and no such difference will be taken into account as part of such Rent Validation. The Parties also will negotiate in good faith to determine (A) whether one
Party should make a lump sum payment to the other Party as a result of excess or deficient Rent that Lessee paid, prior to the date of the effective date of the Rent Validation, in connection with the Rent Supplement, and, (B) if applicable,
the amount of any such lump sum payment. The Parties will memorialize the result of any Rent Validation negotiation by executing and delivering a revised Rent Supplement, which will set forth revised expected Incremental CapEx, Lessee CapEx, Base
Rent, Percentage Rent Percentages, Annual Percentage Rent Breakpoints and/or Revenues Attributable to Lessee CapEx, as applicable, the effective date on which such changes will occur and, if applicable, the amount of the lump sum payment that one
Party must make to the other Party (which payment must be made within 30 days of the execution and delivery of such revised Rent Supplement). 

  

					
		  	10	  	CREZ ASSETS LEASE AGREEMENT









 
Any lump sum payments received by Lessor under this Section 3.2(c) shall be treated as Rent by the Parties. Upon execution and delivery of any such Rent Validation, this Agreement will be
deemed amended thereby. 
 (ii) For the avoidance of doubt, notwithstanding expiration of the Initial Term on
December 31, 2020, upon request of either Party made at any time before March 1, 2021, the Parties will conduct a Rent Validation pursuant to this Section 3.2(c) in order to determine (I) whether one Party should make a lump sum
payment to the other Party as a result of excess or deficient Rent Lessee paid, prior to the date of the effective date of such Rent Validation, in connection with the Rent Supplement, given any negotiated supplement, and, (II) if applicable, the
amount of any such lump sum payment. The provisions of this Section 3.2(c) will apply to any such lump sum payment. 

(iii) The Parties will reasonably cooperate to minimize the number of Rent Validations, and prospective Rent Supplements and
Rent Validations may be combined into one revised, amended and restated Rent Supplement. 
 (d) In connection with the foregoing provisions
of this Section 3.2, Lessor and Lessee shall use good faith efforts to agree to a Rent Supplement, renewal of a Rent Supplement or Rent Validation, as applicable, within 60 days of a request therefor by either Party. If, by the end of such 60
day period, Lessee and Lessor cannot in good faith agree to the terms of a Rent Supplement, renewal of a Rent Supplement or Rent Validation, such dispute shall be submitted to arbitration in accordance with Section 13.7, pursuant to which the
Arbitration Panel shall be empowered to determine the terms of such Rent Supplement, renewal of a Rent Supplement or Rent Validation (including any lump sum payment amount), based on submissions by each of the Lessee and the Lessor. 

3.3 Confirmation of Percentage Rent. 

(a) In the event that Lessee determines that the Percentage Rent paid with respect to any Lease Year exceeded the amount of Percentage Rent
actually due for such Lease Year (such overage being the “Excess Percentage Rent”), Lessee shall promptly notify Lessor of such fact and shall deliver a new CFO Certificate (the “Revised Certificate”) setting forth
the corrected calculations of the Percentage Rent due for such Lease Year and identifying the amount of the Excess Percentage Rent. Upon Lessor’s reasonable verification of the information set forth in the Revised Certificate, Lessor shall
refund to Lessee the Excess Percentage Rent. Notwithstanding anything to the contrary contained herein, in no event shall Lessor have any obligation under this Section 3.3(a) to refund any Excess Percentage Rent if Lessor has not received the
Revised Certificate by March 31 of the year following the Lease Year for which the Excess Percentage Rent was paid. 
 (b) Lessee shall
utilize, or cause to be utilized, an accounting system for the CREZ Assets in accordance with the FERC Uniform System of Accounts, that will accurately record all data necessary to compute Percentage Rent, and Lessee shall retain and shall allow
Lessor and its representatives to have reasonable access to, for at least five (5) years after the expiration of each Lease Year, reasonably adequate records conforming to such accounting system showing all data necessary to conduct
Lessor’s Audit and to compute Percentage Rent for the applicable Lease Years and to otherwise file or defend tax returns and reports to any Regulatory Authority. 

  

					
		  	11	  	CREZ ASSETS LEASE AGREEMENT









 (c) Lessor shall have the right from time to time to cause its accountants or representatives to
conduct an inspection, examination and/or audit (a “Lessor’s Audit”) of all of Lessee’s records, including supporting data, sales and excise tax returns and the records described in Section 3.3(b), reasonably required
to complete such Lessor’s Audit and to verify Percentage Rent, subject to any prohibitions or limitations on disclosure of any such data under applicable laws, regulations and governmental requirements. If any Lessor’s Audit discloses a
deficiency in the payment of Percentage Rent, and either Lessee agrees with the result of Lessor’s Audit or the matter is otherwise determined or compromised, Lessee shall forthwith pay to Lessor the amount of the deficiency, as finally agreed
or determined, together with interest at the Overdue Rate from the date when said payment should have been made to the date of payment thereof. In addition to the amounts described above in this Section 3.3(c), if any Lessor’s Audit
discloses a deficiency in the payment of Percentage Rent which, as finally agreed or determined, exceeds 3% of the amount paid, Lessee shall pay the costs of Lessor’s Audit. In no event shall Lessor undertake a Lessor’s Audit after
March 31 of the second year following the Lease Year for which such audit is requested. 
 (d) Any proprietary information obtained by
Lessor pursuant to the provisions of this Section 3.3 shall be treated as confidential, except that such information may be used, subject to appropriate confidentiality safeguards, in any litigation or arbitration between the Parties and except
further that Lessor may disclose such information to lenders and investors, including prospective lenders or investors and to any other persons to whom disclosure is necessary or appropriate to comply with Applicable Laws, regulations and
governmental requirements and to comply with any reporting requirements applicable to Lessor or Lessee under any applicable securities laws or regulations or any listing requirements of any applicable securities exchange. 

(e) Any dispute as to the existence or amount of any deficiency in the payment of Percentage Rent as disclosed by Lessor’s Audit shall,
if not otherwise settled by the Parties, be submitted to arbitration pursuant to the provisions of Section 13.7. 
 3.4
Additional Rent. In addition to Base Rent and Percentage Rent, Lessee also will pay and discharge as and when due and payable all other amounts, liabilities, obligations and impositions that Lessee assumes or agrees to pay under this
Agreement, including without limitation, the expenses and costs described in Section 1.3 and any reimbursement for such amounts and other damages to Lessor in the event that Lessor pays such expenses or costs or performs such obligations on
behalf of Lessee (collectively, “Additional Rent”). 
 3.5 No Set Off. Rent shall be paid to Lessor
without set off, deduction or counterclaim; provided, however, that Lessee shall have the right to assert any claim or counterclaim in a separate action brought by Lessee under this Agreement or to assert any mandatory counterclaim in
any action brought by Lessor under this Agreement. 

  

					
		  	12	  	CREZ ASSETS LEASE AGREEMENT









 3.6 Late Payment Penalty. Except as otherwise provided in
Section 9.1(b), if Lessee fails to make any payment of Rent to Lessor within five (5) days after it is due, interest shall accrue on the overdue amount, from the date overdue until the date paid, at the Overdue Rate. 

3.7 Credit Support. If Lessor has reasonable grounds for insecurity regarding the performance of Lessee’s
obligations hereunder, Lessor may require Lessee to provide credit support in the amount, form and for the term reasonably acceptable to Lessor, including but not limited to, a letter of credit, a prepayment, or a guaranty. 

3.8 Other Revenue. If Lessee receives or expects to receive any fees, charges or Other Revenue and other than de minimis
amounts not to exceed $100,000 in any calendar year, then, unless Lessee reasonably believes that such Other Revenue will not operate to reduce Lessee’s tariff within the State of Texas, Lessee and Lessor will negotiate in good faith to amend
this Agreement or a similar lease to characterize the portion of such Other Revenue which Lessor reasonably expects will operate to reduce Lessee’s tariff within the State of Texas as Unadjusted Gross Revenue hereunder or under such other
similar lease. In the event the Lessee and Lessor cannot agree on the terms of such amendment of this Agreement or of a similar lease, then either the Lessee or the Lessor may submit such matters to arbitration pursuant to Section 13.7,
pursuant to which the Arbitration Panel shall be empowered to characterize the portion of such Other Revenue which Lessor reasonably expects will operate to reduce Lessee’s tariff within the State of Texas as Unadjusted Gross Revenue hereunder
or under such other similar lease, based on submissions by each of the Lessee and the Lessor. 
 3.9 Survival. The
obligations of Lessee and Lessor contained in this Article III with respect to the calculation, validation and payment, including late payment, of Rent applicable to periods prior to the end of the Term shall survive the expiration or earlier
termination of this Agreement. 
 ARTICLE IV 

LESSEE’S REPRESENTATIONS, WARRANTIES AND COVENANTS 

Lessee hereby represents, warrants and covenants to Lessor that: 

4.1 Maintenance, Operation and Repair of the CREZ Assets. 

(a) Lessee, at its own cost and expense, shall maintain (including both scheduled and unscheduled maintenance), operate, repair and make all
modifications (other than the construction of Footprint Projects, which shall be subject to Article X) to the CREZ Assets and any components thereof (whether owned by Lessor or Lessee), including directing all operations of and supplying all
personnel necessary for the operation of the CREZ Assets, in each case, as reasonable and prudent and consistent with Good Utility Practice and as required by Applicable Law. Lessee shall carry out all obligations under this Agreement as reasonable
and prudent and consistent with Good Utility Practice and in accordance with manufacturers’ warranty requirements (during any applicable warranty period) and the Lessee’s established operating procedures and maintenance, rebuild and repair
programs so as to keep the CREZ 

  

					
		  	13	  	CREZ ASSETS LEASE AGREEMENT









 
Assets in good working order, ordinary wear and tear excepted, and in such condition as shall comply in all material respects with all Applicable Laws. Lessee will operate the CREZ Assets in a
reliable and safe manner in compliance with all applicable requirements and regulations of Regulatory Authorities. Lessee will not operate the CREZ Assets or any component thereof in any manner excluded from coverage by any insurance in effect as
required by the terms hereof. 
 (b) If inspections of the CREZ Assets by Lessor show that the CREZ Assets do not meet industry standards or
Good Utility Practice for maintenance and repair and/or fail to meet the requirements of any Applicable Law, Lessee shall promptly, but in any event within thirty (30) days after such initial notification, (i) develop a plan for
Lessor’s review by which the CREZ Assets can be modified or replaced to comply with the standards, and (ii) complete any and all such modifications and/or replacements consistent with all applicable reliability and safety standards
established by regulations, orders or requirements of Regulatory Authorities. 
 4.2 Licenses and Permits. Lessee shall
obtain and maintain any and all licenses, permits and other governmental and third-party consents and approvals required by Applicable Law in order to carry out its obligations under this Agreement. 

4.3 Property Taxes and Other Assessments and Fees. Lessee shall bear (or collect from customers, as applicable) and
timely pay all ad valorem or property taxes, sales and use taxes, or other assessments, governmental charges or fees that shall or may during the Term be imposed on, or arise in connection with, the ownership, lease, repair, maintenance and/or
operation of, the CREZ Assets (including all Footprint Projects as described and provided for in Section 10.1 of this Agreement) (excluding any Lessor Taxes, “Lessee Taxes”); provided that Lessee shall not be obligated
to pay any income, franchise or similar taxes imposed upon Lessor any consolidated, combined unitary or similar group that includes Lessor or any direct or indirect owner of an equity interest in Lessor, or any transfer, recordation, sales, use or
similar taxes which arise in connection with Lessor’s acquisition of Footprint Projects or the construction of Footprint Projects funded by Lessor (“Lessor Taxes”). The Parties understand that Lessee collects certain Lessee
Taxes from end customers and remits such payments to the appropriate Regulatory Authority, and that nothing in this Section 4.3 is intended to impose liability on Lessee (instead of such customer) for the related tax liability beyond that
imposed by Applicable Law with respect to such collection obligations. Upon the written request by Lessor, Lessee shall provide Lessor with evidence of the payment of any such Lessee Taxes, the failure of which to be paid would cause the imposition
of a Lien upon the CREZ Assets or any component thereof or interest therein. Lessee shall assume full responsibility for preparing and furnishing to Lessor for execution all filings with any Regulatory Authority of or in the state and/or locality in
which the CREZ Assets are located in respect of any and all Lessee Taxes; except that, where required or permitted by Applicable Law, Lessee shall make such filings on behalf of Lessor in the name of Lessor or in Lessee’s own name. In each case
in which Lessee furnishes a tax return or any other form to be executed by Lessor for filing with or delivery to any taxing authority, Lessee shall certify to Lessor that such document is in the proper form, is required to be filed under Applicable
Law and does not impose any tax or other liability on Lessor or any of its affiliates which is not indemnified by Lessee. Lessee shall be permitted to contest, in its own name when permitted by law but otherwise on behalf of Lessor, in good faith
and upon consultation with Lessor, any taxes it is obligated to pay hereunder. 

  

					
		  	14	  	CREZ ASSETS LEASE AGREEMENT









 4.4 Requirements of Governmental Agencies and Regulatory Authorities.
Lessee, at its expense, shall comply with all Applicable Laws, including without limitation all requirements of the Regulatory Authorities. Lessee shall have the right, in its reasonable discretion and at its cost and expense, to contest by
appropriate legal proceedings, the validity or applicability to the CREZ Assets of any Applicable Law made or issued by any federal, state, county, local or other Regulatory Authority. Any such contest or proceeding shall be controlled and directed
by Lessee. Lessee shall provide Lessor with written notice of the commencement of any such legal proceedings that relate to or are a Lessor Material Matter. Thereafter, if requested by Lessor, Lessee will update Lessor, at reasonable intervals, of
the progress of any such proceedings that relate to or are a Lessor Material Matter. 
 4.5 Liens. Lessee shall keep
the CREZ Assets free and clear of all Liens other than Permitted Liens; provided, however, that if Lessee wishes to contest any such Lien (other than a Permitted Lien), Lessee shall, promptly, and in any event within thirty
(30) days after it receives notice of the filing of such Lien, remove or bond over such Lien from the CREZ Assets pursuant to Applicable Law. If Lessee fails to promptly remove or bond over any such Lien, Lessor may, after providing notice to
Lessee, take reasonable action to satisfy, defend, settle or otherwise remove the Lien at Lessee’s expense. 
 4.6 Hazardous
Materials. 
 (a) Lessee shall operate and maintain the CREZ Assets and conduct all of its other activities in respect thereof in
compliance in all material respects with any Environmental Laws and other Applicable Laws relating to air, water, land and the generation, storage, use, handling, transportation, treatment or disposal of Hazardous Materials. Lessee shall promptly
notify Lessor of any such violation that is a Lessor Material Matter. To the extent Lessee becomes aware of any environmental, health, safety or security matter that requires a corrective action, Lessee shall (in consultation with Lessor in the case
of any Lessor Material Matter) undertake and complete such corrective action. Lessee shall have the obligation to report any such violations to the appropriate Regulatory Authorities in accordance with Applicable Law and, if practicable, shall give
notice thereof to Lessor prior to making such report with respect to any Lessor Material Matter. 
 (b) Without limiting the generality of
the foregoing, Lessee shall not (i) place or locate any underground tanks on the property underlying the CREZ Assets, (ii) generate, manufacture, transport, produce, use, treat, store, release, dispose of or otherwise deposit Hazardous
Materials in or on the CREZ Assets, the property underlying the CREZ Assets or any portion thereof other than as permitted by Environmental Laws that govern the same or are applicable thereto, (iii) permit any other substances, materials or
conditions in, on or emanating from the CREZ Assets, the property underlying the CREZ Assets or any portion thereof which may support a claim or cause of action under any Applicable Law or (iv) undertake any action that would reasonably be
expected to cause an unauthorized release of Hazardous Materials at the property underlying the CREZ Assets. 
 (c) Lessee shall
periodically, at intervals determined in its reasonable discretion in accordance with Good Utility Practice or as required by Applicable Law, at Lessee’s sole expense, conduct inspections of all components of the CREZ Assets to ensure
compliance with Applicable Laws and with this Section 4.6, and shall promptly notify Lessor of the results of any such inspections. Lessor may, at Lessor’s expense, conduct its own testing at times determined in its reasonable discretion,
and after reasonable consultation with Lessee, to ensure Lessee’s compliance with Applicable Laws and with this Section 4.6, provided, however, that Lessor agrees to indemnify Lessee from and against any and all Claims
suffered or incurred by Lessee and arising from Lessor’s testing in accordance with Section 12.2. 

  

					
		  	15	  	CREZ ASSETS LEASE AGREEMENT









 4.7 Indebtedness. Lessee shall not incur Indebtedness other than:
(i) Indebtedness in an aggregate principal amount of up to the greater of (A) $5,000,000 and (B) an amount equal to one percent (1%) of the sum of, without duplication, (x) the total amount of the Consolidated Net Plant of
Lessee, plus (y) the total amount of the Consolidated Net Plant of any guarantor(s) of Lessee’s obligations under any Lease to which Lessee is a party as a lessee, plus (z) the total amount of Leased Consolidated Net Plant of Lessee,
in each case on a senior secured basis, (ii) Indebtedness in an aggregate principal amount of up to the greater of (A) $10,000,000 and (B) an amount equal to one-and-a-half percent (1.5%) of the sum of, without duplication,
(x) the total amount of the Consolidated Net Plant of Lessee, plus (y) the total amount of the Consolidated Net Plant of any guarantor(s) of Lessee’s obligations under any Lease to which Lessee is a party as a lessee, plus
(z) the total amount of Leased Consolidated Net Plant of Lessee, in each case on an unsecured subordinated basis on terms substantially similar to the terms set forth on Exhibit C and (iii) loans, in an aggregate principal amount
not to exceed $10,000,000 at any time outstanding, made by InfraREIT Partners, LP or a subsidiary thereof to Lessee from time to time for the purpose of financing capital expenditures. For purposes of clauses (i) and (ii) of the preceding
sentence, any Consolidated Qualified Lessees of Lessee will be treated as Lessee. In addition to the foregoing, any of Lessee’s subsidiaries may incur Indebtedness in an aggregate principal amount of up to the product of (x) Lessee’s
aggregate Consolidated Net Plant multiplied by (y) the lesser of (A) the sum of Lessee’s then-current PUCT-regulated debt-to-equity ratio (expressed as a percentage) and five percent (5%) or (B) sixty-five percent (65%);
provided, however, that such Indebtedness must be Non-Recourse Debt to Lessee. For purposes of this Section 4.7, Lessee’s Consolidated Net Plant will be derived from its most recently prepared consolidated balance sheet,
prepared in accordance with GAAP but adjusted to reverse the effects of failed sale-leaseback accounting in a manner reasonably determined by Lessee in good faith. Without limiting the amount of Indebtedness permitted by the foregoing, Lessee may
also incur Indebtedness (x) in the form of a pledge of equity interests in a subsidiary of Lessee as security for Non-Recourse Debt of such subsidiary and (y) in amounts otherwise permitted under the Debt Agreements. 

4.8 Records. In addition to the records referred to in Section 3.3, Lessee shall maintain proper books of record and
account in conformity with GAAP and all applicable Regulatory Authorities having legal or regulatory jurisdiction over Lessee. Additionally, Lessee shall maintain or cause to be maintained all logs, drawings, manuals, specifications and data and
inspection, modification and maintenance records and other materials required to be maintained in respect of the CREZ Assets by Applicable Laws or by Good Utility Practice. Lessee shall allow Lessor and its representatives to have reasonable access
to, for at least five (5) years after the expiration of each Lease Year, the records referred to in this Section 4.8. 

  

					
		  	16	  	CREZ ASSETS LEASE AGREEMENT









 4.9 Surrender. Upon expiration or earlier termination of this Agreement in
accordance with its terms (but subject to Section 2.2 and the requirements of all Applicable Laws), and in a manner calculated to avoid any disruption of electrical service, Lessee shall vacate and surrender possession of all components of the
CREZ Assets (other than in respect of Footprint Projects funded by Lessee as described in Section 10.5(a)) to Lessor, or to such other Person as Lessor may direct. At the time of such surrender, the CREZ Assets shall be free and clear of Liens
and other rights of third parties (other than Permitted Liens), and shall be in the same condition as the date the construction of such CREZ Assets was completed, ordinary wear and tear and subsequent Footprint Projects excepted. Lessee shall
deliver or cause to be delivered to Lessor, or to such other Person as Lessor may direct, copies of all title documents, logs, drawings, manuals, specifications and data and inspection, modification and maintenance records, billing records, reports
and other documents in respect of the CREZ Assets which are necessary to determine the condition of the CREZ Assets or for the continued maintenance, repair or general operation of the CREZ Assets and are in Lessee’s possession or control at
such time. In connection with the surrender of the CREZ Assets, Lessor shall pay to Lessee the aggregate purchase price for any Footprint Projects, equipment or other property purchased by Lessor in accordance with Section 2.3 or
Section 10.5(b). 
 4.10 Cooperation; Transition Services. 

(a) During the period after notice of termination and prior to the termination of the Agreement, with reasonable notice, Lessee will cooperate
in all reasonable respects with the efforts of Lessor to sell or lease the CREZ Assets (or any component thereof) or any interest therein, including, without limitation, permitting prospective purchasers or lessees to fully inspect the CREZ Assets
and any logs, drawings, manuals, specifications, data and maintenance records relating thereto; provided that such cooperation shall not unreasonably interfere with the normal operation of the CREZ Assets or cause Lessee to incur any
additional expenses other than as specifically provided herein. All information obtained in connection with such inspection shall be subject to confidentiality requirements at least as restrictive as those contained in Section 13.3. 

(b) Upon expiration or termination of this Agreement, Lessee shall continue to lease and operate the CREZ Assets pursuant to the terms of
Section 2.2, if required thereunder. During such period Lessee shall perform all duties and retain all obligations under this Agreement in all respects, as if the Agreement had not expired or been terminated, and will pay Extended Period Rent

 ARTICLE V 

LESSOR’S REPRESENTATIONS, WARRANTIES AND COVENANTS 

Lessor hereby represents, warrants and covenants as follows: 

5.1 Lessor’s Authority. Lessor has all requisite power and authority to execute and deliver this Agreement and to
perform its obligations hereunder. Lessor has taken all action necessary to execute and deliver this Agreement and to perform its obligations hereunder, and no other action or proceeding on the part of Lessor is necessary to authorize this
Agreement. This Agreement constitutes the legally valid and binding obligation of Lessor, enforceable against Lessor in accordance with its terms, except as the enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar Applicable Laws affecting the enforcement of creditors’ rights generally and equitable principles. 

5.2 Liens and Tenants. Lessor represents that Lessor has good and valid title to the CREZ Assets, there are no unrecorded
liens, encumbrances, leases, mortgages, deeds of trust (except as disclosed to Lessee in writing or as arise by operation of law), or other exceptions (collectively, “Liens”) arising as a result of any acts, or omissions to act, of
Lessor by, through or under Lessor to Lessor’s right, title or interest in the CREZ Assets other than any such of the foregoing that does not materially impair the Lessee’s use of the CREZ Assets, and, to Lessor’s knowledge, there
exist no rights or interests of any third party relating to the CREZ Assets that are not contemplated herein. Except for Permitted Liens or as may be disclosed in the applicable real property records in the State of Texas, or as disclosed by Lessor
in writing to Lessee, Lessor represents that there are no Liens encumbering all or any portion of the CREZ Assets. Lessor shall fully cooperate and assist Lessee, at no out-of-pocket expense to Lessor, in efforts to obtain a subordination and
non-disturbance agreement from each party that holds a Lien that might reasonably be expected to interfere in any material respect with Lessee’s rights under this Agreement. Notwithstanding the foregoing, Lessor and its affiliates shall have
the right to incur Permitted Liens encumbering the CREZ Assets or any component thereof solely for the benefit of Lessor in connection with any existing or future financing or refinancing pursuant to which the CREZ Assets (or any component thereof)
is pledged as collateral and Lessee agrees to enter into such acknowledgments and agreements in respect thereof with the lenders, or a trustee or agent for the lenders as the Lessor may reasonably request. 

5.3 Condition of Assets. Lessor has not taken any action or failed to take any action that would cause the CREZ Assets
not to be in good operating condition and repair, ordinary wear and tear excepted, or adequate for the uses to which it is being put. 

5.4 Requirements of Governmental Agencies. Lessor shall assist and fully cooperate with Lessee, in complying with or
obtaining any material land use permits and approvals, building permits, environmental impact reviews or any other approvals reasonably required for the maintenance or operation of the CREZ Assets, including execution of applications for such
approvals, and including participating in any appeals or regulatory proceedings respecting the CREZ Assets at Lessee’s cost and expense, if requested by Lessee. 

  

					
		  	20	  	CREZ ASSETS LEASE AGREEMENT









 5.5 Hazardous Materials. Lessor shall conduct its activities in respect of
the CREZ Assets in compliance in all material respects with applicable Environmental Laws. 
 5.6 Litigation. If Lessor
becomes aware of any actions, claims or other legal or administrative proceedings that are pending, threatened or anticipated with respect to, or which could materially and adversely affect, the CREZ Assets, Lessor shall promptly deliver notice
thereof to Lessee. 
 5.7 Records. Lessor shall maintain proper books of record and accounts in conformity with GAAP
and all applicable Regulatory Authorities and each other governmental agency or authority having legal or regulatory jurisdiction over Lessor. 

5.8 Limitation. EXCEPT AS EXPRESSLY REPRESENTED OTHERWISE IN THIS ARTICLE V, LESSOR (A) MAKES NO AND EXPRESSLY
DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO (I) TITLE TO THE CREZ ASSETS OR ANY PORTION THEREOF, (II) ANY ESTIMATES OF THE VALUE OF THE CREZ ASSETS OR FUTURE REVENUES THAT MIGHT BE GENERATED BY THE CREZ ASSETS, (III) THE
MAINTENANCE, REPAIR, CONDITION, QUALITY, SUITABILITY, DESIGN OR MARKETABILITY OF THE CREZ ASSETS, (IV) INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHT OR (V) ANY OTHER MATERIALS OR INFORMATION THAT MAY HAVE BEEN MADE AVAILABLE OR COMMUNICATED
TO LESSEE OR ITS AFFILIATES, OR ITS OR THEIR EMPLOYEES, AGENTS, CONSULTANTS, REPRESENTATIVES OR ADVISORS IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY DISCUSSION OR PRESENTATION RELATING THERETO, AND (B) FURTHER
DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR CONFORMITY TO MODELS OR SAMPLES OF MATERIALS OF ANY PORTION OF THE CREZ ASSETS, IT BEING EXPRESSLY UNDERSTOOD AND AGREED BY THE
PARTIES HERETO THAT THE CREZ ASSETS ARE BEING LEASED “AS IS, WHERE IS,” WITH ALL FAULTS AND DEFECTS, AND THAT LESSEE HAS MADE OR CAUSED TO BE MADE SUCH INSPECTIONS AS LESSEE DEEMS APPROPRIATE. 

ARTICLE VI 
 LOSS AND
DAMAGE; INSURANCE 
 6.1 Loss and Damage to the CREZ Assets. 

(a) In the event of any damage or loss to any component of the CREZ Assets, Lessee shall promptly repair or replace such component to the
standards required by Section 4.1 (regardless of whether such repair or replacement constitutes a Repair or a Footprint Project). Notwithstanding anything to the contrary contained in this Agreement, any such repaired or replaced component will
immediately become part of the CREZ Assets owned by Lessor and the cost of any repair or replacement shall be borne as described in Sections 6.1(b)-(d) below. 

  

					
		  	21	  	CREZ ASSETS LEASE AGREEMENT









 (b) If such repair or replacement constitutes a Repair, the cost of repairing or replacing such
damage or loss, whether actually covered in whole or in part by insurance, shall be the responsibility of Lessee. In such circumstance, unless otherwise agreed by the Parties, (i) if the damage or loss is covered by insurance, Lessee shall be
responsible for payment of any deductible, and (ii) any damage or loss not covered by insurance (exclusive of any deductible) shall be the responsibility of Lessee. If the sum of such deductible and insurance proceeds exceeds the cost of such
Repair, then Lessee will retain such excess. 
 (c) If such repair or replacement constitutes a Footprint Project, then, as long as the
related costs have been included in a CapEx Budget, the cost of repairing or replacing such damage or loss, whether actually covered in whole or in part by insurance, shall be the responsibility of Lessor. In such circumstance, unless otherwise
agreed by the Parties, (i) if the damage or loss is covered by insurance, Lessor shall be responsible for payment of any deductible, and (ii) any damage or loss not covered by insurance (exclusive of any deductible) shall be the
responsibility of Lessor. If the sum of such deductible and insurance proceeds exceeds the cost of such Footprint Project, then such excess will first reduce Lessor’s obligation to fund the deductible hereunder, and any excess thereafter will
be retained by Lessor. If such repair or replacement constitutes a Footprint Project that is not included in a CapEx Budget, the provisions of Article X shall apply. 

(d) Lessee shall be solely responsible for all costs of repairing or replacing any damaged property and equipment that is not part of the CREZ
Assets and owned by Lessee, whether covered by Lessee’s insurance under Section 6.2 or otherwise. Nothing in this provision shall preclude Lessee from seeking recovery of such costs in a rate proceeding at the PUCT. 

(e) If Lessor funds Lessee’s Personal Property pursuant to Section 10.1(b) of this Agreement, then all such funded Personal Property
will be treated as a Footprint Project, and not a Repair, for purposes of this Section 6.1. 
 6.2 Insurance.
Lessee will maintain, with financially sound and reputable insurers, insurance with respect to its business and properties and the CREZ Assets against such casualties and contingencies, of such types, on such terms and in such amounts (including
deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar
business and similarly situated, but in no event less than the insurance set forth in this Section 6.2 and Exhibit B. 
 (a)
Lessee shall procure at its own expense and maintain in full force and effect at all times throughout the term of this insurance policies with insurance companies rated A-, 8 or higher by A.M. Best or acceptable to Lessor if not so rated, and
authorized to do business in the State of Texas. 
 (b) Lessor may at any time amend the requirements and approved insurance companies
described in this Section 6.2 or Exhibit B due to (i) new information not previously known by Lessor prior to the date of this Agreement or (ii) changed circumstances after the date of this Agreement, which in the
reasonable judgment of Lessor either renders a required coverage to be materially inadequate or materially reduces the financial ability of the approved insurance companies to pay claims. 

  

					
		  	22	  	CREZ ASSETS LEASE AGREEMENT









 (c) On the first Business Day of each year, and promptly at such other times as Lessor may
reasonably request, Lessee shall furnish Lessor with approved certification of all required insurance. Such certification shall be executed by each insurer or by an authorized representative of each insurer where it is not practical for such insurer
to execute the certificate itself. Such certification shall identify underwriters, the type of insurance, the insurance limits, and the policy term, and shall specifically list the special provisions enumerated for such insurance required by this
Section 6.2 and Exhibit B. Upon request, Lessee will promptly furnish Lessor with copies of all insurance certificates, binders, and cover notes or other evidence of such insurance relating to the CREZ Assets. 

(d) Concurrently with the furnishing of the certification referred to in Section 6.2(c) and on an annual basis thereafter, Lessee shall
furnish Lessor with a certificate, signed by an officer of Lessee, stating that all premiums then due have been paid and that the insurance then carried or to be renewed is in accordance with the terms of this Section 6.2. and Exhibit B.

 (e) In the event Lessee fails to take out or maintain the full insurance coverage required by this Section 6.2 and Exhibit B,
Lessor, upon thirty (30) days’ prior notice (unless the aforementioned insurance would lapse within such period, in which event notice should be given as soon as reasonably possible) to Lessee of any such failure, may (but shall not be
obligated to) take out the required policies of insurance and pay the premiums on the same. All amounts so advanced thereof by Lessor shall become an additional obligation of Lessee to Lessor, and Lessee shall forthwith pay such amounts to Lessor.

 (f) No provision of this Section 6.2 or Exhibit B or any other provision of this Agreement, shall impose on Lessor any duty
or obligation to verify the existence or adequacy of the insurance coverage maintained by Lessee (nor shall any action taken, or not taken, by Lessor to verify the existence or adequacy of the insurance coverage maintained by Lessee affect the
obligations of Lessee pursuant to this Section 6.2), nor shall Lessor be responsible for any representations or warranties made by or on behalf of Lessee to any insurance company or underwriter. 

ARTICLE VII 
 REPORTING

 7.1 Financing Arrangements. 

(a) Lessee understands that Lessor, or an affiliate thereof, has raised equity and/or debt that may be secured by the CREZ Assets and this
Agreement and that Lessor or its affiliates have reporting obligations in connection with such arrangements, including obligations to provide financial statements prepared in accordance with GAAP, to prepare an annual strategic plan and to update
such annual strategic plan in the event of certain material deviations therefrom. Lessee understands that Lessor relies on Lessee in order to comply with such obligations. From time to time, Lessor or an affiliate thereof may enter into additional
arrangements that impose similar obligations. 

  

					
		  	23	  	CREZ ASSETS LEASE AGREEMENT









 (b) Accordingly, Lessee agrees to provide Lessor in a timely manner: 

(i) audited year-end financial statements and quarterly unaudited financial statements for the first three quarters of each
year; and 
 (ii) such acknowledgements, certificates, permits, licenses, instruments, documents and other information as
Lessor may reasonably request from time to time in connection with, or to enable Lessor and its affiliates to comply with any such debt or equity financing arrangements or with Applicable Law. 

The Parties will negotiate in good faith the time frames during which Lessee will provide such information, with the intention that Lessee provide such
information in a manner that is not unduly burdensome but that also allows Lessor sufficient time to comply with its reporting obligations. 

(c) Lessee agrees that the unaudited interim financial statements provided pursuant to this Section 7.1 will be SAS 100 reviewed, and
Lessee agrees to use commercially reasonable efforts to cause its auditors to consent to the inclusion of their opinion regarding Lessee’s financial statements in filings with the SEC made by Lessor or an affiliate of Lessor (collectively, the
“SEC Reporting Requirements”). Lessor may also request that Lessee provide evidence of a SAS 100 review from Lessee’s auditors with respect to any unaudited interim financial statements included in any such filing. In addition
to including Lessee’s financial statements in the SEC filings of Lessor or an affiliate thereof, Lessor shall have the right to share any such financial statements with any party entitled to review such financial statements pursuant to the
terms of any Debt Agreement. 
 (d) Lessee represents, warrants and covenants that (i) the financial statements provided pursuant to
this Section 7.1 will fairly present in all material respects the financial condition, results of operations and cash flows of Lessee as of, and for, the periods presented, and (ii) Lessee will endeavor to cause such financial statements
to comply with any Applicable Laws, rules or regulations that Lessee and Lessor conclude in good faith are applicable to such financial statements by virtue of their inclusion in the securities law filings of Lessor or an affiliate of Lessor. 

(e) Lessee agrees that, in connection with any underwritten offering of the securities of Lessor or any affiliate thereof, Lessee will use
commercially reasonable efforts to cause its auditors, at Lessor’s cost, to provide a comfort letter (or its equivalent) to such underwriters, if requested by Lessor. 

(f) Lessee will also cooperate with Lessor to enable Lessor to satisfy its obligations in respect of annual strategic plans, including
providing Lessor with requested information in advance of the due date of such annual strategic plan and keeping Lessor apprised of deviations in capital expenditures, construction activity or revenues of Lessee from amounts that were originally
provided by Lessee in preparing such annual strategic plan. 
 (g) Lessee shall, at the earliest practicable time, advise Lessor if Lessee
will be unable to meet the reporting requirements set forth herein in a timely manner and to reasonably cooperate with Lessor to remedy the effects of such non-compliance. 

  

					
		  	24	  	CREZ ASSETS LEASE AGREEMENT









 7.2 Public Company and Regulatory Information and Cooperation. 

(a) Lessee agrees to cooperate with Lessor when Lessor or an affiliate provides estimates to analysts and or investors regarding Lessor’s
expectations of its future operating results (including capital expenditures) and to cooperate with Lessor with respect to analysts and investors to the extent such expectations change in any material respect. 

(b) Lessee and Lessor agree to reasonably cooperate to ensure that, to the extent they require information from the other Party in order
(i) to prepare their financial statements, (ii) to obtain audits of those financial statements and, if required, of their internal control over financial reporting, (iii) to respond to comments of the SEC on such financial statements
or statements related to internal control over financial reporting or disclosure controls and procedures, or (iv) to ensure the efficacy of their internal controls or disclosure controls and procedures, they will reasonably cooperate in order
to ensure that each Party is able to meet its obligations in respect thereof. 
 (c) Lessee agrees to promptly notify Lessor of or provide
to Lessor, as applicable, (i) any material communication, written or otherwise, submitted to Lessee by its auditors, including, but not limited to an audit response letter, accountant’s management letter or other written report submitted
to Lessee by its accountants or any Regulatory Authority in connection with an annual or interim audit of Lessee’s books, (ii) any material correspondence with, reports of or reports to any Regulatory Authority with respect to the CREZ
Assets and (iii) any notices of violations of Applicable Law with respect to the CREZ Assets, in each case taking into account Lessor’s and any of its affiliates’ reporting obligations with the SEC. 

(d) Lessor agrees to inform Lessee of the time periods in which each of the items identified in this Section 7.2 will be required by
providing written notice thereof to Lessee. Lessee shall, at the earliest practicable time, advise Lessor if Lessee will be unable to meet the reporting requirements set forth herein in a timely manner and reasonably cooperate with Lessor to remedy
the effects of such non-compliance. 
 (e) If Lessor identifies additional matters with respect to which Lessee input, assistance or
information is required in order for Lessor and its affiliates to comply with any applicable securities laws, the rules or regulations of any exchange on which the securities of such affiliate are traded or any similar laws, rules or regulations,
the Parties agree to cooperate and negotiate in good faith in order to determine the manner in which Lessee can provide such input, assistance or information in a manner that positions Lessor and its affiliates to comply in a timely manner with such
laws, rules or regulations, as efficiently as is feasible so as to minimize the burden that the provision of such input, assistance or information imposes on Lessee. 

7.3 Mutual Obligations. Each Party shall as promptly as reasonably practicable furnish or cause to be furnished to the
other Party, upon request from such Party, such 

  

					
		  	25	  	CREZ ASSETS LEASE AGREEMENT









 
information as may be required to enable such Party to file any reports required to be filed with any governmental or Regulatory Authority due to such Party’s ownership interest in or
operation and control of the CREZ Assets, as applicable. 
 ARTICLE VIII 

ASSIGNMENT 
 This Agreement
shall not be assignable by either Party, nor shall the CREZ Assets or any part thereof be subleased by Lessee (except in a manner consistent with Section 1.2(b)), except with the prior written consent of the other Party and the prior approval
of any Regulatory Authority whose approval is required for the effectiveness of such assignment or sublease. For purposes of this Article VIII, an “assignment” by Lessee shall mean and include, in addition to any direct transfer by Lessee
to a third party of all or any part of Lessee’s rights, estate or interests under this Agreement, any direct or indirect, voluntary or involuntary transfer of or encumbrance on all or any part of Lessee’s rights, estate or interests under
this Agreement (i) by operation of law and/or (ii) by direct or collateral transfer of all or any part of the legal or beneficial ownership interest in Lessee by merger, consolidation or otherwise, provided that, in the case of
clause (ii), any such transaction or transactions will only constitute an assignment hereunder to the extent they result (whether in one or a series of transactions) in a Change of Control. Notwithstanding the foregoing, Lessor shall have the right,
without Lessee’s consent but subject to obtaining regulatory approval as described in the foregoing sentence, (a) to assign, pledge or grant a security interest in any or all of its interest in the Agreement to a lender or lenders, or a
trustee acting on behalf of such lenders, in connection with a financing or refinancing in which such interest is pledged as collateral, and Lessee agrees to enter into such acknowledgments and agreements in respect thereof as the Lessor may
reasonably request and (b) to assign its interest in this Agreement to a successor owner of the CREZ Assets.

costs and expenditures or an unforeseen material decline in electricity usage as a result of such event and (ii) such failure is cured within ninety (90) days after the date such Rent was due through Lessee’s payment of the entire
amount of such unpaid Rent, plus interest thereon at a rate equal to six percent (6%) per annum or the maximum rate allowed by Applicable Law, whichever is lesser, from the date such Rent was originally due until the date of payment. 

9.2 Lessor Default. Subject to Section 9.3, Lessor shall be in default in the event any representation or warranty
made by Lessor herein shall prove to have been inaccurate in any material respect at the time made, or in the event Lessor breaches or fails to comply in any material respect with any covenant or agreement contained herein (unless any
representation, warranty, covenant or agreement is already qualified by materiality or a similar qualification, in which case (a) such representation or warranty shall be accurate in all respects and (b) such covenant or agreement shall

ninety (90) days of receiving such Notice of Default. 
 9.4 Remedies. 

(a) Should an Event of Default remain uncured by the Defaulting Party, the Non- Defaulting Party shall have and shall be entitled to exercise
the remedies provided in this Section 9.4 and any and all other remedies available to it at law or in equity, all of which remedies shall be cumulative; provided that the exercise of any remedies hereunder shall be subject to PUCT and
other required regulatory approvals to the extent applicable and the provisions of Section 2.2. 
 (b) In no way limiting the
provisions of Section 9.4(a), in the case of an Event of Default of Lessee, Lessor shall have the right to (i) terminate the Agreement upon notice to Lessee, and recover from Lessee all damages to which Lessor is entitled under Applicable
Laws, (ii) terminate Lessee’s right to use and operate the CREZ Assets (other than leasehold improvements pursuant to Section 10.3) while keeping this Agreement in effect, and recover from Lessee all damages to which Lessor is
entitled under Applicable Laws, and (iii) take reasonable action to cure Lessee’s default at Lessee’s expense; provided that, in the event of a violation of Applicable Laws by Lessee, an emergency or government or regulatory
action in respect of which Lessor, in its reasonable discretion, determines immediate action is necessary, Lessor shall have the right to step in and take such action on behalf of Lessee at Lessee’s cost and expense immediately upon giving
notice to Lessee, notwithstanding any applicable cure period. 
 (c) Any amounts recovered by Lessor from Lessee in the event of a default
shall, to the maximum extent permissible under Applicable Laws, be deemed to be in respect of past or future Rent owing under this Agreement.

 ARTICLE X 

CAPITAL EXPENDITURES 

10.1 Capital Expenditures Generally. 

(a) Lessee has provided to Lessor in the CapEx Budget the approximate amounts of Capital Expenditures that Lessee expects will be needed for
purposes of funding Footprint Projects in each Lease Year through 2018. On or before October 15 of each calendar year, Lessee shall review and revise the CapEx Budget on a rolling three-year basis (which shall include, if applicable, any year
in such three-year period following the end of the then-current Term and assume the renewal of this Agreement pursuant to Section 2.1), taking into account any changed circumstances that (i) make it no longer feasible to incur one or more
of the costs reflected on the prevailing CapEx Budget, (ii) make it necessary to amend the nature or amounts reflected for a particular Footprint Project or (iii) dictate that additional Footprint Projects be added (such budget, as so
updated and revised, is referred to herein as the “CapEx Budget”). Lessee agrees to revise the CapEx Budget to include any Footprint Projects (x) required by Regulatory Authorities or (y) reasonably necessary to satisfy
Lessee’s obligation as a regulated utility to serve its customers or to maintain the safety or reliability of the CREZ Assets. Capital Expenditures included in a CapEx Budget will be included based on the date such Capital Expenditures are to
be incurred (notwithstanding that Incremental CapEx and Lessee CapEx are otherwise measured under this Agreement based on when the assets developed with such Capital Expenditures are placed in service, and not when they are incurred). 

(b) If requested by Lessor, Lessee will also provide an estimate of any Capital Expenditures that Lessee expects for purposes of funding
Personal Property related to the CREZ Assets. If Lessor and Lessee agree, Lessor will fund such Capital Expenditures pursuant to this Agreement, through a loan or through a separate lease. Amounts Lessor provides pursuant to this Agreement to fund
any such Personal Property will be treated in a manner similar to any amounts Lessor provides to fund Footprint Projects for purposes of Section 3.2 and elsewhere herein. Lessee will cause any such Personal Property to be titled in
Lessor’s name and will reasonably cooperate with Lessor in order to enable any secured lender of Lessor or any secured lender of an affiliate of Lessor to perfect its security interest in any such Personal Property. In the alternative, Lessor
may elect to fund such Capital Expenditures through a TRS or to loan (or cause such TRS to loan) Lessee the cash to acquire any such Personal Property in a transaction in which Lessor or a TRS may retain a security interest in such Personal
Property. In such case the Parties shall negotiate in good faith the terms under which Lessor or such TRS shall fund any such Personal Property, including the terms of any lease between Lessee and the TRS or other financing arrangements provided by
the Lessor or the TRS. 
 10.2 Capital Expenditures Funded by Lessor. Lessor agrees to fund
any Footprint Projects contained in the CapEx Budget (as revised from time to time). Lessor’s obligation to fund Footprint Projects pursuant to this Section 10.2 shall include any costs associated with such Footprint Projects that Lessee
is not allowed to recover through its PUCT-approved rates. Any Footprint Projects funded by Lessor under this Section 10.2 shall be deemed to be part of the CREZ Assets upon completion. 

  

					
		  	29	  	CREZ ASSETS LEASE AGREEMENT









 10.3 Capital Expenditures Funded by Lessee.
Except as set forth in this Section 10.3, Lessee may not fund any Footprint Projects. In the event Lessor fails to fund any Footprint Projects, Lessee may at its sole discretion fund the needed capital expenditures (and Lessee shall be entitled
to applicable damages, if any, as a result of funding any such Footprint Projects); provided that, in such circumstance, Lessee may fund Severable Footprint Projects without restriction under this Section 10.3 but may only fund
Nonseverable Footprint Projects which are required in order to comply with Applicable Law or which are required by any Regulatory Authority. Subject to Section 10.5, any Footprint Projects funded by Lessee under this Section 10.3 shall not
be considered part of the CREZ Assets for purposes of this Agreement; provided however, that any part of the CREZ Assets that is built with CIAC funds shall be considered a leasehold improvement that is part of the CREZ Assets and
reverts to the Lessor upon termination of this Agreement without further payment from Lessor to Lessee under Section 2.3. 
 10.4
Footprint Project Construction Activities. Lessee will either use its personnel, or either Lessee or Lessor will contract with third parties, to construct Footprint Projects. Lessee shall be responsible for the oversight of such
construction activities, regardless of whether the Footprint Project is funded by Lessor or Lessee. Lessee’s construction activities and oversight shall be intended to ensure that such construction is performed in a manner consistent with Good
Utility Practice and Applicable Law and does not adversely affect the reliability and safety of the CREZ Assets or the ERCOT electric grid. In connection therewith, Lessor will reimburse Lessee for all Project Management Costs that Lessee incurs in
connection with constructing such Footprint Project, provided that any costs and expenses of Lessee under this Section 10.4 must be included in any CapEx Budget submitted by Lessee under Section 10.1 or approved by Lessor to qualify
for reimbursement by Lessor hereunder. 
 10.5 Ownership of Footprint Projects. 

(a) Each Footprint Project shall be owned by the Party that funded the Capital Expenditures used to construct such Footprint Project;
provided however, that any part of the CREZ Assets that is built with CIAC funds shall be considered a leasehold improvement that is part of the CREZ Assets and shall revert to the Lessor upon termination of this Agreement without
further payment from Lessor to Lessee under Section 2.3. 
 (b) Upon the expiration or termination of this Agreement, Lessor shall have
the right (but not the obligation) to purchase, subject to required regulatory approvals, any Nonseverable Footprint Projects or Severable Footprint Projects owned by Lessee at the greater of (i) net book value plus ten percent (10%) and
(ii) the fair market value thereof as determined by mutual agreement of Lessor and Lessee. If the Parties fail to agree on the amount of the purchase price, the purchase price shall be submitted to arbitration in accordance with
Section 13.7, pursuant to which the Arbitration Panel shall be empowered to determine the amount of the purchase price, based on submissions by each of the Lessee and the Lessor. Lessee shall be entitled to remove any Severable Footprint
Projects owned by Lessee upon the expiration or termination of this Agreement in the event such Severable Footprint Projects are not purchased by Lessor, subject to any required regulatory approvals. 

  

					
		  	30	  	CREZ ASSETS LEASE AGREEMENT









 10.6 Asset Acquisitions. Lessee and Lessor will cooperate in good faith to
ensure that all CREZ Assets are acquired in Lessor’s name or are acquired by Lessee and subsequently transferred to Lessor. In connection therewith, Lessee agrees (a) to transfer to Lessor all previously acquired CREZ Assets, (b) that
any future-acquired CREZ Assets will be deemed automatically transferred to Lessor, (c) to take reasonable actions as are necessary and appropriate to document the transfer of any such CREZ Assets to Lessor and, if applicable, to memorialize
the security interest in such CREZ Assets required to be granted pursuant to the terms of the Debt Agreements, including through the delivery and recordation of mortgages, deeds of trust or UCC financing statements, and (d) to take reasonable
steps to record the transfer and such security interest in the records of the applicable county or other applicable locale in which the CREZ Assets are located. 

10.7 Reimbursements. From time to time, Lessee may enter into interconnect or similar agreements that obligate the
counterparty to such agreements to reimburse Lessee for Capital Expenditures in certain circumstances. Such reimbursement obligation may, in some circumstances, be accompanied by additional security such as a parent guaranty or a letter of credit.
If and to the extent that (a) Lessor funds Capital Expenditures that are used for the construction or development pursuant to any of these interconnect agreements, and (b) Lessee becomes entitled to assert any reimbursement or other rights
pursuant to any such interconnect agreements, then, unless Lessor agrees otherwise, Lessee will enforce such reimbursement or other rights and will in turn promptly reimburse Lessor for the amount of related Capital Expenditures that Lessor has
funded pursuant hereto. Lessee further agrees to reimburse Lessor for other Capital Expenditures that Lessor has funded pursuant to this Agreement to the extent required by the Policies and Procedures. 

ARTICLE XI 
 REGULATORY
COOPERATION 
 11.1 Jurisdiction. The Parties recognize that (i) the CREZ Assets and the operation thereof are
subject to the jurisdiction of the PUCT and to certain reliability and safety requirements of ERCOT, NERC and TRE, and (ii) Lessee holds CCNs for operation of the CREZ Assets. The Parties agree that, as the lessee hereunder, as operator of the
CREZ Assets and as the holder of the CCNs, Lessee shall be responsible for compliance with all regulatory requirements related to the CREZ Assets, including but not limited to, taking all actions reasonably necessary or advisable to comply with such
requirements; preparing and filing all necessary notices, reports, applications, and other materials with the PUCT, ERCOT, SPP, TRE and NERC; and initiating, prosecuting, defending or participating in any administrative or judicial proceeding
reasonably necessary or advisable to operate the CREZ Assets in an economical and efficient manner. Lessee shall consult with Lessor prior to initiating any rate proceeding with the PUCT to change the rates Lessee can lawfully charge,
provided that, with or without Lessor consent, Lessee shall be authorized to initiate any such rate proceeding. Upon Lessor’s request, Lessee shall file a rate proceeding before the PUCT; provided that, Lessor shall be responsible
for reimbursing Lessee for all costs associated with prosecution of such proceeding requested by Lessor to the extent that such costs are not recoverable in Lessee’s PUCT-approved rates. 

  

					
		  	31	  	CREZ ASSETS LEASE AGREEMENT









 11.2 Cooperation. The Parties agree that during the term of this Agreement
they will cooperate to assure compliance with all Applicable Laws or other lawful requests of any Regulatory Authorities that relate to the CREZ Assets and Lessee’s obligations as the holder of the CCNs and will provide such information to such
Regulatory Authorities as the other Party or such Regulatory Authorities may reasonably request in connection therewith. Lessor further agrees to use its best efforts to cooperate and promptly respond to any lawful requests from Lessee relating to
Lessee’s efforts to comply with all regulatory requirements or to participate in any necessary or advisable legal proceedings, whether judicial or administrative. Each Party shall bear its own costs in complying with this paragraph.

		  	33	  	CREZ ASSETS LEASE AGREEMENT









 
received by reason of any such taking or condemnation, except for that portion of such award, if any, which is expressly awarded for the Lessee’s leasehold interest under this Agreement or
which is awarded for any property owned by Lessee (including any Footprint Projects funded by Lessee). Lessor shall have the right, in its sole discretion, to challenge any condemnation or taking of the CREZ Assets by proper proceedings, and Lessee
shall not institute any such challenge without the prior written consent of Lessor. 
 13.3 Confidentiality. To the
full extent allowed by Applicable Law, each Party (the “Receiving Party”) shall maintain, for the benefit of the other Party (the “Disclosing Party”), in the strictest confidence all information pertaining to the
financial terms of or payments under this Agreement, the Disclosing Party’s methods of operation, methods of the CREZ Assets, and the like, whether disclosed by the Disclosing Party or discovered by the Receiving Party, unless such information
either (i) is in the public domain by reason of prior publication through no act or omission of the Receiving Party or its employees or agents, (ii) was already known to the Receiving Party at the time of disclosure and which the Receiving
Party is free to use or disclose without breach of any obligation to any Person or (iii) is required to be disclosed by the PUCT or other Regulatory Authorities, or must be disclosed in accordance with applicable securities laws or tax laws or

equity investors, lenders, attorneys, accountants and other personal advisors; any prospective purchaser of the CREZ Assets or the direct or indirect owner thereof; or pursuant to lawful process, subpoena or court order; provided that the
Receiving Party, in making such disclosure, advises the Party receiving the information of the confidentiality of the information and obtains the agreement of said Party not to disclose the information.

		  	34	  	CREZ ASSETS LEASE AGREEMENT









 
cooperate with the other Party to effectuate fully the purposes and intent of this Agreement. In no way limiting the foregoing, the Parties shall cooperate to obtain any necessary regulatory
approvals, including, without limitation, providing timely responses to discovery requests, participating in regulatory proceedings to the extent necessary and generally providing assistance as required. 

(b) From time to time, the Parties shall agree to policies and procedures regarding matters arising under this Agreement including, without
limitation, the treatment of Capital Expenditures for canceled Footprint Projects, each Party’s reporting obligations and such additional matters as the Parties may identify (the “Policies and Procedures”). The Parties agree to
cooperate and negotiate in good faith the Policies and Procedures, and any amendment or revision thereto that may be reasonably requested by either Party, and to memorialize the same in a writing executed by a representative of each Party. In the
event the Parties cannot agree on the terms of such Policies and Procedures, then either the Lessee or the Lessor may submit such matters to arbitration pursuant to Section 13.7, pursuant to which the Arbitration Panel shall be empowered to
determine Policies and Procedures that take into account InfraREIT’s reporting obligations as a public company and Lessee’s obligations as a regulated utility. 

13.7 Arbitration. Except for a dispute regarding the payment of Undisputed Rent, any dispute under this Agreement shall,
if not resolved by the Parties within ninety (90) days after notice of such dispute is served by one Party to the other (or, if different, the period provided for resolution by the Parties in the provision of this Agreement under which such
dispute is brought), be submitted to an “Arbitration Panel” comprised of three (3) members. No more than one (1) panel member may be with the same firm, and no panel member may have an economic interest in the outcome of
the arbitration. In addition to the foregoing, the failure by the Lessee and the Lessor to reach an agreement or make a mutual determination or characterization required by Sections 2.2(b); 2.3; 3.1 (the first paragraph thereof); 3.1(d)(i);
3.1(d)(ii); 3.1(d)(iii); 3.2(a); 3.2(d); 3.3(e); 3.8; 10.5(b) or 13.6(b), in each case after 60 days of negotiating in good faith, shall be deemed to be a “dispute” for purposes of this Section 13.7, to be resolved in accordance with
this Section. 
 (a) The Arbitration Panel shall be selected as follows: Within five (5) Business Days after the expiration of the
period referenced above, Lessee shall select its panel member meeting the criteria of the above paragraph (the “Lessee Panel Member”) and Lessor shall select its panel member meeting the criteria of the above paragraph (the
“Lessor Panel Member”). If a Party fails to timely select its respective panel member, the other Party may notify such Party in writing of such failure, and if such Party fails to select its respective panel member within three
(3) Business Days from such notice, then the other Party may select such panel member on such Party’s behalf. Within five (5) Business Days after the selection of the Lessor Panel Member and the Lessee Panel Member, the Lessee Panel
Member and the Lessor Panel Member shall jointly select a third panel member meeting the criteria of the above paragraph (the “Third Panel Member”). If the Lessor Panel Member and the Lessee Panel Member fail to timely select the
Third Panel Member and such failure continues for more than three (3) Business Days after written notice of such failure is delivered to the Lessor Panel Member and Lessee Panel Member by either Lessor or Lessee, either Lessor or Lessee may
request the managing officer of the American Arbitration Association to appoint the Third Panel Member. 

  

					
		  	35	  	CREZ ASSETS LEASE AGREEMENT









 (b) Within ten (10) Business Days after the selection of the Arbitration Panel, each Party
shall submit to the Arbitration Panel a written statement identifying its summary of the issues and claims, including, if applicable, its calculation of Rent. Any Party may also request an evidentiary hearing on the merits in addition to the
submission of written statements. The Arbitration Panel shall make its decision within twenty (20) days after the later of (i) the submission of such written statements of particulars, and (ii) the conclusion of any evidentiary
hearing on the merits, and shall take into consideration the relative risks and rewards undertaken and capital invested by each Party and shall use the Comparable Rate of Return concept described in Section 3.2(a) in determining any Rent
disputes. The Arbitration Panel shall reach its decision by majority vote and shall communicate its decision by written notice to the Parties. 

(c) The decision by the Arbitration Panel shall be final, binding and conclusive and shall be non-appealable and enforceable in any court
having jurisdiction. All hearings and proceedings held by the Arbitration Panel shall take place in Dallas, Texas. 
 (d) The resolution
procedure described herein shall be governed by the Commercial Rules of the American Arbitration Association and subject to the Texas General Arbitration Act to the extent such act is applicable hereto. 

(e) In the case of an arbitration proceeding involving a determination of Rent and Percentage Rent, until Rent and Percentage Rent have been
finally determined, Lessee shall pay Rent and Percentage Rent based upon prevailing rates therefor, and an appropriate refund shall be made to or additional Rent shall be paid by Lessee within ten (10) days after a final determination is made.

 (f) The Parties shall bear equally the fees, costs and expenses of the Arbitration Panel in conducting the arbitration. 

13.8 Notices. All notices or other communications required or permitted by this Agreement, including payments to Lessor,
shall be in writing and shall be served personally or by reputable express courier service or by facsimile transmission addressed to the relevant parties at the address stated below or at any other address notified by that Party to the other as its
address for service. Any notice so given personally shall be deemed to have been served on delivery, any notice so given by express courier service shall be deemed to have been served the next Business Day after the same shall have been delivered to
the relevant courier, and any notice so given by facsimile transmission shall be deemed to have been served on dispatch. As proof of such service it shall be sufficient to produce a receipt showing personal service, the receipt of a reputable
courier company showing the correct address of the addressee or an activity report of the sender’s facsimile machine showing the correct facsimile number of the Parties on whom notice is served and the correct number of pages transmitted. All
communications, other than routine correspondence in the ordinary course of business, between the Parties pursuant to this Agreement shall be sent by the same method of communication by the Party sending the communication. The Parties’

other parties in the manner provided in this Section 13.8. 
 13.9 Entire Agreement; Amendments. This Agreement
and the Policies and Procedures constitute the entire agreement between Lessor and Lessee respecting the subject matter hereof, and supersede any and all oral or written agreements. Any agreement, understanding or representation respecting the CREZ
Assets, or any other matter referenced herein not expressly set forth in this Agreement, in the Policies and Procedures or in a subsequent writing signed by both Parties is null and void. For avoidance of doubt, the Second Amended and Restated Lease
is hereby replaced in its entirety by this Agreement. This Agreement shall not be modified or amended except in a writing signed by both Parties. No purported modifications or amendments, including without limitation any oral agreement (even if
supported by new consideration), course of conduct or absence of a response to a unilateral communication, shall be binding on either Party. 

13.10 Legal Matters. This Agreement shall be governed by and interpreted in accordance with the laws of the State of
Texas, without regard to its conflicts of law principles. The Parties agree that any rule of construction to the effect that ambiguities are to be resolved in favor of either Party shall not be employed in the interpretation of this Agreement and is
hereby waived. 
 13.11 Partial Invalidity. Should any provision of this Agreement be held, in a final and unappealable
decision by a court of competent jurisdiction, to be either invalid, void or unenforceable, the remaining provisions hereof shall remain in full force and effect, unimpaired by the holding. 

13.12 Recording. Lessee shall not record this Agreement without the prior written consent of the Lessor. Lessee may
record at its expense a memorandum of this Agreement in form and substance reasonably approved by Lessor. 

  

					
		  	37	  	CREZ ASSETS LEASE AGREEMENT









 13.13 Intention of Parties; True Lease. 

(a) The Parties hereby declare that their relationship in and to the CREZ Lease Assets is and will be that of lessor and lessee, expressly
subject to the terms, conditions, limitations and requirements set forth in this Agreement. Nothing contained in this Agreement will be deemed to constitute the Parties as partners or joint venturers or as principal and agent. The Parties intend for
this Agreement to constitute a true lease with respect to the CREZ Lease Assets for US Federal, state and local income tax purposes, and each Party shall treat the Agreement as a true lease with respect to the CREZ Lease Assets for federal income
tax reporting purposes. 
 (b) The Parties acknowledge that Lessor is indirectly owned, in part, by InfraREIT, which qualifies as a real
estate investment trust (“REIT”) under the Code, and the Parties agree to negotiate in good faith any modification or amendment to this Agreement requested by Lessor to facilitate such qualification; provided that Lessee
shall not be obligated to agree to any such modification or amendment if such modification or amendment would materially adversely affect Lessee or would be in conflict with Applicable Law or any regulations or orders of any Regulatory Authority.
Notwithstanding anything to the contrary in this Agreement (including Section 13.3), Lessor may disclose to InfraREIT, and InfraREIT may disclose to any taxing authority, any information that Lessor or InfraREIT believes is relevant to
supporting or maintaining InfraREIT’s qualification as a REIT. 
 13.14 Rules of Construction. As used herein, the
singular shall be deemed to include the plural, and the plural shall be deemed to include the singular, and all pronouns shall include the masculine, feminine and neuter, whenever the context and facts require such construction. The headings,
captions, titles and subtitles herein are inserted for convenience of reference only and shall not affect the interpretation of this Agreement. Except as otherwise indicated herein, all section, appendix, exhibit and schedule references in this
Agreement shall be deemed to refer to the sections, appendices, exhibits and schedules of and to this Agreement, and the terms “herein,” “hereof,” “hereto,” “hereunder” and words of similar import refer to
this Agreement as a whole rather than to the particular provision in which such term is used. Whenever the words “including,” “include” or “includes” are used in this Agreement, they shall be interpreted in a
non-exclusive manner as though the words “but [is] not limited to” immediately followed the same. The language in all parts of this Agreement shall in all cases be construed simply according to the fair meaning thereof and not strictly
against the party that drafted such language. Except as otherwise provided herein, references in this Agreement to any agreement, instrument or other document are to such agreement, instrument or other document as amended, modified or supplemented
from time to time.

2. Payment of Loss Proceeds. The Collateral Agent, on behalf of the Secured Parties, shall be named as the first loss payee in

 4. Waiver of
Subrogation. Lessee hereby waives any and every claim for recovery from the Secured Parties for any and all loss or damage covered by any of the insurance policies to be maintained under this Agreement to the extent that such loss or damage is
recovered under any such policy. If the foregoing waiver will preclude the assignment of any such claim to the extent of such recovery, by subrogation (or otherwise), to an insurance company (or other Person), Lessee shall give written notice of the
terms of such waiver to each insurance company which has issued, or which may issue in the future, any such policy of insurance (if such notice is required by the insurance policy) and shall cause each such insurance policy to be properly endorsed
by Lessee to, or to otherwise contain one or more provisions that prevent the invalidation of the insurance coverage provided thereby by reason of such waiver. 

5. Notices. Lessee will advise Lessor in writing promptly of (i) any material changes in the coverage or limits provided under any
policy required by Section 6.2 of this Agreement and this Exhibit B and (ii) any default in the payment of any premium and of any other act or omission on the part of Lessee which may invalidate or render unenforceable, in whole or

investigate all losses on behalf of the insurers. 
 4. Policy Cancellation and Change. All policies of insurance required to be
maintained pursuant to this Exhibit B shall be endorsed so that if at any time they are canceled, or their coverage is reduced (by any party including the insured) so as to affect the interests of the Collateral Agent, the Holders and any
other Secured Party, such cancellation or reduction shall not be effective as to the Secured Parties for thirty (30) days, except for non-payment of premium which shall be for ten (10) days, after receipt by the Collateral Agent and the

insurance policies providing operational property damage, (i) shall name the Collateral Agent, on behalf of the Secured Parties, as the first loss payee, (ii) shall include a Lender’s loss payable clause in favor of the Collateral
Agent, on behalf of the Secured Parties.

Section 3. Liquidation, Dissolution, Bankruptcy. Until the indefeasible payment in full in cash of all the Obligations and the termination of any
commitments to lend under any Permitted Secured Indebtedness, and without limitation to the rights of the Secured Parties under the terms of the Financing Agreements or the rights of Company under the System Leases: 

 

	3.1	upon the occurrence and during the continuance of any Insolvency Event: 

  

	 	3.1.1	the System Lease Obligations then due and payable shall first be irrevocably and indefeasibly paid in full to the Entitled Party before any of the Subordinated Lenders shall be entitled to receive any payment (other
than Reorganization Securities) on account of the Subordinated Indebtedness whether in cash, securities or other assets (other than Reorganization Securities); 

  

	 	3.1.2	any payment or distribution of assets of Sharyland of any kind or character in respect of the Subordinated Indebtedness to which any of the Subordinated Lenders would be entitled if the Subordinated Indebtedness were
not subordinated pursuant to the terms hereof shall be made by the trustee, liquidator or agent or other Person making such payment or distribution, directly to the Entitled Party until the System Lease Obligations then due and payable are paid in

 Section 4. Incorrect Payments. If, for any reason whatsoever and whether pursuant to an Insolvency

respect of the Subordinated Indebtedness in contravention of any of the terms set forth herein, such Subordinated Lender shall hold any such payment or distribution in trust for the benefit of the Secured Parties, promptly notify the Entitled Party

the Subordinated Lender’s obligations, liabilities, agreements or duties hereunder, or affect the provisions set forth herein in any way.

Parties, the Collateral Agent, the Company, the Subordinated Lenders, and their respective successors and permitted assigns. 
 Section 7.
Termination and Reinstatement. Notwithstanding anything to the contrary contained herein, the Subordinated Indebtedness shall no longer be subordinated in right of liquidation pursuant to the terms contained herein otherwise at such time as
the Secured Parties no longer have a lien on or security interest in the System Lease Obligations. If any payment to any of the Entitled Party, the Company, the Collateral Agent or the Secured Parties by Sharyland or any other Person in respect of
any of the System Lease Obligations is held to constitute a preference or a voidable transfer under applicable Law, or if for any other reason any such party is required to refund such payment to Sharyland or to such Person or to pay the amount
thereof to any other Person, each Subordinated Lender agrees and acknowledges that the provisions set forth herein shall continue to be effective or shall be reinstated, as the case may be, to the extent of any such payment or payments. 

Section 8. Restrictions on Transfers. None of the Subordinated Lenders may transfer (by sale, novation or otherwise) any of its rights or

Section 9. Exercise of Powers. 
  

	9.1	After the occurrence and during the continuance of an Insolvency Event, the Entitled Party shall be entitled to exercise its rights and powers under these subordination provisions in such a manner and at such times as
the Entitled Party in its absolute discretion may determine. 

  

	9.2	The Subordinated Lenders alone shall be responsible for their contracts, engagements, acts, omissions, defaults and losses and for liabilities incurred by them.
